Quality Control

Our production of [1,1'-Biphenyl]-4-Carboxylic Acid, 3-Amino-4'-Methoxy- adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to verify identity, potency, and impurity profiles. We provide detailed Certificates of Analysis (COA) with every shipment, documenting all critical quality attributes. Our quality system is designed to support applications requiring GMP-grade or research-grade materials, and we are committed to meeting relevant industry and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
